I see. Your complaint is that in vehicles that are staffed only with a driver, the driver refuses to handle change, and that -in your youth- your parents didn't provide you with any information (whether directly from them, or published by your local transit authority) about how mass transit worked in your area.

There's not much the transit authority can do about your parents' decision to leave you ill-informed. I can tell you that obligating the solo driver to handle change would be significantly user-hostile for the passengers currently on the vehicle. The tradeoff made is the correct one.

As you're probably aware, there's also good news: for a while now, many (most?) transit systems permit payment with radio cards that are linked to a preexisting pool of money, rather than having to handle cash inside the vehicle.
